Abstract
A switching regulator including a control circuit including a deviation detector for detecting a deviation between the detection value of the controlled variable and the reference value, a phase difference signal generator for generating a phase difference signal having a pulse width corresponding to the deviation, a reference signal shaper for shaping two reference signals of the same waveform having a phase difference corresponding to the pulse width of the phase difference signal, and a control signal generator for ON/OFF control of switching elements corresponding to the reference signals for controlling a switching circuit having transistors connected as the switching elements in a bridge formation, the switching elements are all driven with an equal ON/OFF ratio, the phase difference between the ON instructions to the two sets of the switching elements is controlled to control the output so that the control of the switching regulator is accomplished not by the pulse width for driving the switching elements but by the overlapping width of ON times of the two switching elements.
